- To all whom it may concern Be it known that I, PHILIP T. Doves, a citizen of the United States, and a resident of \Vashington, District of Columbia, have invented a new and useful Improvement; in Line-Casting'Machines, of which the following is a specification.

My invention has reference to line casting machines of the Mergenthaler system, in which circulating matrices representing individual characters, stored in a magazine, are delivered by means of finger keys, assembled temporarily in line, with suitshle spacing devices, and the line presented ternporarily to a mold to form ty e characters on the edge of a slug cast t erein; after which the line of matrices is elevated to e distributing mechanism, bywhich the individual matrices are returned to the appropriate channels in the magazine.

The invention relates more particularly to those-machines in which superposed magazines, each carrying a font or series of matrices, are movable vertically at the will of the attendant in order that one or another of the magazines may be brought into operative ,relation to the distributing mechanism above and the assembling mechanism below, as first shown in Letters Patent of the United States No. 548,432 issued to me on the 22d day of October 1895.

In the machine described in this patent the escapements are located in a stationary throat forming a continuation of the magszine in operatlve position, and the organization is such that two matrices from each channel are normally held in this throat, outside of the magazine. Before it is pos sible to efi'ect the adjustment of the magazines it isnecessary to push these matrices backward into the magazine-a ver v diiiicult operation--01 to pass them through the machine :indthrough the distributing mecha nism, in order to restore them to the mag azine.

The main objects of the present invention are as follows:

The first ObJQCt is to avoid the retention of nmtrices beyond the lower end of the magnzine, so that the adjustments of the megazines may be made at any instant, and Without loss of time. i i

To this end theinvention consists in comhining, with movable magazines a series of external escepements so constructed and ar Specification of Letters Patent.

ranged that each matrix released from. c magazine 18 permitted to pass directly to the line in course of composition,

The second object of the invention is provide for the automatic locking ofthe matrices within those magazines which t re not for the time being in use, and for 1 automatic unlocking of the matrices in ear.

. magazine as it is brought to the operative position. 7

To this end it consistsin combining with the magazine means for locking the matrices therein and means for automatically actuating said locking devices.

With the exception of the parts hereinafter specifically described the machine may he of the construction represented in the abovejnazned patent or of the construction shown in application for l etters Patent filed by J. R. Rogers on May 1st, 1911, Seriel i-lo. 62 L326.

said channels and delivers them successively to the usual assembling or composing mechanism.

E, E, E etc, are a series of superposed magazines, each consisting of two parallel platessecured to intermediate blocks, and grooved longitudinally in their inner opposing faces, to guide the upper and lower edges or the matrices which are delivered into the upper end of the magazines from the distributor, and delivered, in turn, from the lower end of the magazine into the face plate C.

F is a base frame on which the series of magazines are supported; G a column fixed to and supporting the base frame; and H, a sleeve or tube forming part of the mainframe, and serving to guide the column G.

l is a screw mounted in the lower end of the sleeve H, for the purpose of raising and lowering the column G and the series of magazines.

J is an actuating gear secured to the lower end of the s rew and receiving motion from the gear K, which is in turn connected by a jointed shaft L, to a hand crank M, at the front of the machine, so that by turning the crank the attendant may raise or lower the magazines, bringing any one of the series into operative relation with the distributing and assembling mechanism.

N is a locking bar mounted to slide endwise in bearings on the mainframe, and ar-- ranged to engage at its ends in grooved plates (1', secured to the frame which sustains the magazines. this bar serving to lock the magazine which is for the time being in use solidly and accurately in position, so that its upper and lower ends will be in exact alineinent with the coiiperating parts.

All of the parts so far as described may be identical in construction with those shown in the lingers application above rch'rrod to. or cl' any other suitabl construction. nrv invention having no reference thereto.

ln carrying my in'vi-ntion into etl'cct l mount on the n'iainirame a stationary throat l, having internal fIl0()\' or channels forming continuations of those in tlnmagazine which for the moment in opi-rnlim e tion. 1 iii: ihzoat is designed in ri-rrivc and Ell iil'sll'li guide lhr outcoming nhtriccs al and cot them downward the Fare plate.

For the purpose of cll'octing lllv deliver of th; umtriccs one at a time from the ungazinc, l 'novilhe on Lin: HXu-l side of the. stationary throat l". 1 so of c ripenuts one For each rlmnm-l the magazin These 0; :apcment may hr made of v sinus lj'ormsbut in the. t wn shown they con ist on ch of a lover .munted at or near the middle on a horizontal pivot and having at opposit ends two lips or studs-extending upward through openings in the underside of the spacing I threat, the form and arrangement being such The lip at the upper end of the escapement stands normally in the position shown in full lines in Figs. 2 and 6, so that it engages agalnst the outer or lower end of the foremost matrix, holding the same in the magazine. When the position of the escape ment isreversed the upper lip is retracted and the matrix permitted to escape from one magazine, while at the same time the lower lip is elevated to such a position that it engages the lower end of the outcoming matrix, as shown in Fig. 9, momentarily arresting its advance. matrix thus arrested bears against and holds back within the magazine, the second matrix, which has advanced to take. its place. The escapement is next returned to its original position; whereupon its upper end ongages and holds the second matrix within the magazine, at the same time releasing the first one, and permitting if: to pass downward to the line in course oi composition.

The escapement is acted'upon by a spring y, which normally holds its upper cud in the elevated position shown in Figs. 2 and 7.

In order to permit the engagement of the escapement with the front oi the second matrix, Within the magazine, while it is being held back by the first or detained matrix. I prefer to cut away the upper end of the matrices on the under sides asshown in Figs. land 9 and at w in Fig. ,S. This recess may be of angular form, as shown in Fig; 8, or the car of the matrix may be beveled, as in Fig. 10, the only requirement being that space shall be afl'orded between the upper end of one matrix and the lower end of the next for the admission of the cscapement.

The action of the esuapcnwntmay be effected by any suitable nwans. preferably by vertical read it guided in the main Frame, and lifted atintorvals by a rain mechanism sin-h as shown. controlled in its action by a linger lfll', H The cam mrclmnism shown l identical with that commonly used in .U rg nthalor machines of the present day and described in detail in Letters latcntf the l niicd States No. SSOJJIH ilssurd to inc on December.'l rllhi 159i. As this mochanlsm is familiar to all skillrd in the art, it is deemed l n resszarv to describe its details herein.

\lhenevvr u lingrr low is operated the reed it is lifted 1 iw-lianicallv. and the escapement inovwl against the action of the spring, and lhen lchusril Unit the escapement may be restored to its originulposh tion, the effect being the release m a matrix whenever a key is depressed.

It will he observed that the final release The upper end of the 'ing in action. For-this purpose 1 of the matrix is effected by the second move' ment of the escapement, that-no matrix is permanently retained outside of themagazinc, and that inthis important respect the structure shown differs from that shown i my Patent 5%,432.

.the matrices and ermit them to pass freel as shown in the magazine next to the top one in Fig. 2; while on the other hand, if the shaft is given a quarter rotation, so that its vertical face is perpendicular to .the path or the matrices, it willengage the upper ears of the lowermost matrices and lock them within the magazine, the same time forcing thematrioes sli htly upward within the magazine, so that t eir lower ex-.- tremities will not protrude, or contact with any external surfaces. These shafts are not individually claimed, as they form the subject matter of Letters Patent of the United States No. 776,719, granted to me December 6th, 190%, F or the purpose of turning these shaft-s automatically, 1 provide each of them at the outer end with a crank arm 2, preferably with an anti-friction roller at the extremity, and 1 mount on the main; frame a vertical flange or guide, U, against which these crank arms travel as the megazines are raised and lowered. At a point just above the operative magazine this guide U is provided with a hinged portion u, which may be turned backward or downward, as fiiown in dotted lines, to afiord an opening through which the crank arm on the operative ma azine will swing, as indicated in dotted lines in Fig. 3, thus turn- .ing the shaft to a position to unlock the matrices. When this hinged portion is re stored to its original position it turns the crank, and causes the rock shaft to lock the matrices in the operative magazine before that magazine is moved from the operative position. This movement may be, efiected by any suit-able means, but I prefer, as shown in Fig. 1, to provide the member u with a crank arm a, connected by a link M2, to a lever 14 which actuates the locking bar N as heretofore, This lever u is connected by a link a an angular lever u, and a rod a, with a plate u fconnecmd to the hand crank, so that when this crank is pushed inward as in the -Rogers application, to unlock the magazines, it will at the sEme time cause the member u to turn the rock shaft and lock the matrices in that magazine which is in use. On the other hand, whenever a magazine is raised or lowered to the operative level, the crank on its rock shaft will bebrought opposite the member to, and when the bar N is moved to lock the magazines the member at will permit the rock shaft to, unlock the matrices, so that they may be discharged by the escapements.

The weight of the matrix columns tends to turn the rock shafts from the locked to the unlocked position, but I prefer to apply to each shaft a coiled spring 1;, tending to turn it to the unlocked position.

From the foregoing it will be understood that whenever the magazines are to be raised or lowered, the matrices will be locked, within the magazines, in advance of their movement, and that whenever a magazine reaches the operative position its matrices alone will be unlocked and made subject to the control of the escapements.

While I prefer to make use of the rock shafts as the best means for locking the matrices within the magazines, and to operate them by means of crank arms as described, it is to be understood that any equivalent mechanism, carried by the magazines, may be employed; and that the looking mechanism may be actuated by any suitable devices. a

It is also to be understood that the escapements may be varied in form, provided that they have a mode of'action substantially the same as'hercin shown, the requirements be ing that they shall by the first movement re lease a matrix from the magazine, and by a second or final movement discharge the first matrix and hold the second Within the magazine. It will/be understood that two,'threc or four magazines may be employed: and it is also to be understood that in place of the Mergenthaler distributing mechanism herein shown, any other suitable means may be employed for returning the matrices to the upper end of the o erative magazine, these means,which are oreign to my invention, being already known in various forms to persons skilled in the art.

My invention is of course applicable to machines which'carry matrices for type, and to machines which carry type dies or type in the magazinem short to all typographic machines in which circulating type members are employed. v
